INTRODUCTION Since the genus Rhynchosciara belongs, like Chironomus, to the suborder Nematocera it will be very interesting to see if the formation of its salivary secretion proteins is similar to that of Chironomus secretion or to Bombyx silk biosynthesis . Moreover, this work will be of importance for a better understanding of the hemolymph protein function and will provide a basis for improv...

Some adult eusocial bees have a pair of cephalic salivary glands (CSG) in addition to the thoracic labial or salivary gland pairs. This paper deals with variations in morphological features and secretion production of the CSG of females and males of Apis mellifera Linnaeus, 1758 and Scaptotrigona postica Latreille, 1807. The following life stages were studied: newly emerged, nurse, and forager ...
